Robert Whitworth (1734 – 30 March 1799) was an English land surveyor and engineer, who learnt his trade under John Smeaton and James Brindley, and went on to become one of the leading canal engineers of his generation.
Whitworth was born in Sowerby, West Riding of Yorkshire to Henry and Mary Whitworth. He was baptised on 15 November 1734, and was their sixth child of seven. His father worked as a combsmith, and the family lived in a house called Waterside or Wheatleyroyd, where he probably lived until he married Sarah Irwin on 26 December 1765. After a brief period in Norton in the Moors around 1772, Whitworth and his family, which by now included two sons, returned to Sowerby, and stayed there until the 1790s. During the latter part of this period he lived in Waterside, but moved to Burnley for the final years of his life, to be closer to the Leeds and Liverpool Canal, on which he was working. He died on 30 March 1799 at the White Lion Inn in Halifax, aged 64.
Details of Whitworth's early life have not been found, but in 1761 he produced plans of an estate in Erringden, by which time he was a qualified land surveyor. He undertook a variety of tasks, which included measuring the stonework of Sowerby Church, so that the contractors who had built it could be paid the correct amount, and conducting a survey of the religious affiliations of families in Sowerby. Although its purpose is unknown, he surveyed part of the River Calder and produced a plan. The engineer John Smeaton had been working on the Calder and Hebble Navigation since 1759, working upstream from Wakefield. There is no direct evidence to connect the two men, but it seems likely that Whitworth would have taken an interest in such a significant project, and that he learnt a great deal from watching Smeaton's methods.
Smeaton was replaced by James Brindley as the engineer for the Calder and Hebble project in 1765, and again there is no direct evidence to link the two men at this stage, but plans for the Huddersfield Broad Canal, produced for Sir John Ramsden in 1766, are variously attributed either to Brindley or to Whitworth, and by 1767, Whitworth had become the chief surveyor and draughtsman within Brindley's organisation. There are a number of cases where Brindley was able to obtain commissions for survey work because of his reputation, but the work was then delegated to Whitworth to carry out. During this period he produced plans for the Staffordshire and Worcestershire Canal's Birmingham to Aldersley Junction route, the canal from Coventry to Fradley Heath on the Trent and Mersey Canal, the Droitwich Barge Canal and the Oxford Canal. He also attended Parliament to assist Brindley during the 1767–68 session.
